PARKER GLASS GATHERING DEVICE Filed Aug. 2'7, 195]. 2 Sheets-Sheet 2 Patented Oct. 13, 1936 UNITED STATE-s This application relates to a glass gathering device and more particularly to an improvement in gathering. devices for bulb machines and the like. This invention is an improvement upon that disclosed in Kadow Patent 1,223,393 dated April 24, 1917, which in turn is an improvement'over the gathering device disclosed in Kadow Patent 1,527,556 dated February 24, 1925; The details of the mechanism withwhich this improvementfis particularly designed to'cooperate may be'found inthe aforesaid patents.

In accordance with the present invention, there is only one gathering ramemployed which is used in turn with a plurality of shaping devices. Ihe shaping devices travel continuously, and the ram travels with thosedevices while it is delivering glass thereto, then travels jintoan adjacent furnace, moves, while gathering'glass in a direction opposite to the movementof the glass'shaping devices, and then returns with the gathered glass from the furnace to the pathofthe'shapin d vices. Thismethod' ofoperation is one of the features of the invention, and the mechanism by iwhich" itjis icarried out is another feature of the invention; Detail'sjan'd other objects of the invention. .will more fully appear as the description proceeds."

In the accompanying drawings forming a part of this specification Figure 1 is a plan view of the improved mechanism for operating the ram together with a diagrammatic showing of the ram and associated glass shaping mechanism and glass furnace;

Figure 2 is a vertical section of the parts shown in Fig. 1, taken longitudinally beside the ram; and

Figures 3 and 4 are detail views similar to Fig. 1, but showing the parts in different positions.

In this construction there is a ram I0 which slides upon an inclined carrier II mounted to oscillate about a column I2. Within column I2 there is a hollow shaft I3 on the upper end of which there is mounted a cam plate I4. Within the hollow shaft I3 there is a shaft l5 upon the upper end of which there is an eccentric I6 operating a rod ll in connection with the operation of the ram. Beneath carrier I I there is a rotatable turret I8 carrying a plurality of glass shaping units, those indicated on Fig. 1 being designated I 9 I 9' and I9. There may be one or more glass shaping devices in connection with each unit, but in the construction illustrated there are shown two glass receiving spindles 2B in connection with each unit. These spindles are adapted to receive glass from the gathering ram, manipulate the gatherers, and ultimately shape into the lfor'fone revolution of .the'plate, sliding the ram outward and inward twice for each revolution of desired articles,'the details or this operation roifming nopart off the present invention.

The ram car'ries two gathering cups 2!, and is moved'longitudinally of inclined carrier II by a rack 22 which-engages a gear 23 on a stub shaft 5 2 1, which also carries a smaller gear '25 engaging "a'rack 26 on a slide 21. Slide 21 has on its upper ege-r 116; 28 working in a slideway 29 in a slide 30, which lismounted in a guideway 3I in a stationary'member 32. Camplate I4 has on its 10 lower sidea cam groove 33 which operates aroller 34 'on'the' upper "side of slide tlla In the construction shown, ca m'groove133 is shapedwith two equal parts, so that it repeats its operation twice lsha'ft'f'l'ef'jand plate l4.- Mounted'in e bers:

fthere is f a'vertical rockshaft 35 on the upper end 'o f whfich there is'an arm.3 6 carryinga roller 31 which, is operatedby a cam groove 38 on theupper sideof platejl t, 9n its lower end, rock shaft 35 "c rriesan'arm' 3 9 connected by alink II) to ram [ElfllCam groove j38 is likewise shaped with two equal parts soasit'o repeat its cycle of movements "twice during each [revolution of plate I4. 1 5

h The operation of :thefdevicej will b'effairIy apparent from'the description given, but"may be briefly summarized as follows:

Beginning with the position shown in Fig. 4, and in the dotted line position of the rams in 30 Fig. 2, it will be seen that the gathering cups 2| are dipping into the glass. At this time roller 31 is operated by cam 38 to move the ram in a reverse direction from that in which the glass shaping devices are moved. The gathering cups thus move, during the gathering operation, in the dotted line paths designated M on Fig. 1, during which time they are actually in contact with the glass. This tends to set up a current of glass in the pool. When they reach the end of this portion of their travel, roller 31 encounters a concentric portion of the cam groove 38 while roller 34 is moved by cam groove 33 to withdraw the ram from the furnace into the position in which it is shown in Fig. 1, the parts being timed so that the gathering cups 2| then register with the glass receiving members 20. Roller 31 then is operated by cam groove 38 to move the ram and its carrier II synchronously with the shaping devices during theportion of their dotted line travel designated on Fig. 1 by 32. During this time the glass is dropped from the gathering cups and taken by the receiving members 20. At the end of this portion of travel of the gathering cups, roller 31 enters another 55 concentric portion of groove 38 while roller 34 is'operated by groove 33 to move the ram outward and return it to the position in which it is shown in Fig. o 4, whereupon the operation is repeated. 7 V l 7 By this construction and arrangement the glass is delivered to the shaping devices without haltreceiving members. Thereafter the gathering shaping devices. In this way, there :is but one ram necessary for each shaping mechanism,

although in the form illustrated thereare two I r gathering cups on each ram and 'two'gl'ass reresults in the, gathering ram being'inrsubstan tially constant use and 'sufliciently heated by the ceiving members oneach shaping device. This glass so that no extra heating isfrequir'ed to ke'ep the gatheringcups atthe proper working temperature for rapid operation. In fact during normal operation, cooling is desirable, or even necessary, and may be iaccomplished'in anysuitgable manner. 7 At the same time the cups are ''moved through theglass while gathering in such a way as to set up a circulation of the glass where- V 1 by the glass {out rr'om'tne cup, as the cu is V. withdrawn iron; the furnace, iscarried on beyond the; point where .the, cup] will next engage the glass." In'this way the cut oil glass is given" 7 ample time for remelting before it again returns to the path of the gathering cup; or. if desired, l means maybe employed to prevent any portion or'theglass, chilled by cutting, 'froinreturni' 'ng to the path of the gathering cup. 'By movement ,of the'gathering devices withthe'receiving meme bersfduring the discharge'operation and in a direction opposite thereto during gathering operation, the desired-.movement 'of the'cups durin both operations is accomplished with a of total movement of the cups.

While one mechanism for embodying this inaosaos vention has been described in considerable detail, 7

it will be understood that other operating de vices may be employed within the terms of the appended claims. 7
